Application filed July 12,

rious parts more fully described in the fol-v lowing specification and pointed out in the annexed claims.

In the accompanying drawings Figure 1 is a longitudinal section of the strainer; r

Fig. 2 is across sectional view of the same taken on line 22 of Fig. 1;

v Fig. 3 is an elevation view of the strainer receptacle and fittings therefor;' Fig. 4 is a detail view of the screen securing means; i 5 is a plan view. of the securing ring for t e strainer receptacle; and

Fi 6 is an enlarged fragmentary sectiona view of theupper end of the strainer,

showing the manner of suspending the -receptacle from the strainer body.

, outlet'passage 11,- the latter Like numerals of rferencein the drawingtdesignate correspondin parts;

eferring now. to? the i-awin g.;; Reference character indicates astrainrbody provided with an inlet passa e 12," and an 7 aving a suitable controlling valve 13. f The bottom of the body 10 is formedfwith anxinternally threaded downward exten ing'flang'e' 14, and inside the .latter is another flange -having diametrically o posite horizontal slots 16.

There is provi ed a screen 17 suitably secured to a rin% frame 18. which is adapted to fit over said ange 15, being secured there-- to by a C shaped 1ocking r1ng'19, having outwardly extending lobes 20, which protrude through slots 16 and engage with the lower edge of the screen frame 18, thus removably securing, the screen .17, to the strainer body. F 1 I ,The strainer rece tacle com rises a cup like member 21 mi e preferab y of a suitable light sheet metal and having its upper end formed with an outside flange 22,fa1}1ld o t e stramerbody, and enclose screen 1 7. The side of the receptacle near the top thereof is formed with one or more vertical ribs 9,

1926. Serial No. 121,843;

which are cut away, as indicated zit-23, for" the reception. ofa locking wire 24 (see Fig. 3) Fitted, about the top of the receptacle and abutting the, underside of the flange 22 and held in place by said locking wire 24, is an annular exteriorly threaded member 25 for securing said receptacle in position within the flange 14.. Betweenthe flange 22 and the strainer body, a gasket 26 is fitted whereby leakage is prevented at said connection.

Member 25 is preferably provided with one or more internal circular recesses 26 for preventingarelative movement between it and the receptacle as the same is screwed home: comp'ressmg said gasket and efiecting a liquid tight connection around said flange of receptacle.

From the foregoing, it will be seen that there is provided a novel and practical means of securing a. metal receptacle to the strainer body without involving the process of formmg screw threads on the wall thereof, whereby thinner-metal for the receptacle may be utilized and which includes a simple and lnexpensive device for holding the said means 1n posltion upon said receptacle; and furthermore, a simple and inexpensive means for removably attaching the strainer screen to the strainer frame is provided.

Modification of the above may be made wlthin the spirit and scope ofthe invention.

WhatIclaimis:

1; A strainer receptacle formed with an 0 en, flanged upper end, and having vertical r i 3 about the wall ofthe receptacle, said r bs provided with transverse cutaway portrons. a

2. A strainer receptacle formed with an o en,flanged upperend, having vertical ribs a outthe wall of the receptacle, said ribs provlded withtransverse cutaway portions,

and an exteriorly threaded ring having 1nprovided with transverse cutaway portions,

an exteriorly threaded ring having internal circular recesses to adapt the same to fit about said, ribs and under flange of said receptacle, and means to removably secure said ring under said flan e.

4. Thecombination w1th a strainer recep-.

tacle having an open flanged upper end, and the upper wall provided with broken vertical ribs extending upward to said-flange, of an annular extension threaded member of an internal diameter corresponding to the external diameter of the top of said receptacle, and provided with circular recesses for adapting the same to fit over the upper portions of said ribs, and a locking wire to lie in the broken sections of said ribs for hold ing said member in engagement with the underside of said flange.

5. In a strainer for gasoline vacuum systems, the combination with a strainer body having inlet and outlet passageways and ports, a flange surrounding the inletport formed with diametrically opposite transverse slots, a spring within said flange having lobes extending outward from said slots, and a screen frame arranged about said flange and resting upon said lobes whereby the same is removably secured to said strainer body.

6. A strainer body havin a flange surrounding the inlet port provlded with horizontal slots, a screen mounted on said flange, and a spring arranged in said slots for rerflnovably holding said screen on to said an e.

7. In a strainerfor liquids the combination with a strainer frame having inlet and outlet ports and passageways, a depending flange surrounding inlet port and forme with diametrically opposite transverse slots, and an exteriorly threaded depending flange about said inner flangeand including said outlet port, of a screen fitted about said inner flange having an upper securing frame, a C- shaped locking wire disposed within the flange having projecting lobes extending through said slots in the flange and adaptet to engage with said screen frame and removably support said screen about the inlet port, an open flanged receptacle adapted to fit within said outer flange, a gasket interposed between the flange and strainer body, an exteriorly threaded ring adapted to engage with said threaded flange of strainer body and receptacle flange whereby the receptacle is held in position in a liquid tight connection, and means for making said annular member rigid-with the receptacle.

In testimony whereof I affix my signature.
